The growth of cancer cells in the stomach is referred to as stomach cancer. There are different types of stomach cancer which are dependent on the type of cells that develop the tumor.
Symptoms of stomach cancer
Some of the signs and symptoms of stomach cancer are as follows:
- Bloating sensation after eating
- Increased satiety even after eating little
- Pain in the stomach
- Loss in weight
Causes of stomach cancer
- The exact cause of stomach cancer is unknown. It is believed that mutations of the DNA in stomach cells result in stomach cancer.
- A diet that is low in vegetables and fruits, smoked foods and high salt diet; presence of stomach polyps; consumption of foods adulterated with aflatoxin fungus; Helicobacter pylori infection; a family history of stomach cancer; chronic inflammation of the stomach; smoking and pernicious anemia increase the risk to developing stomach cancer
Treatment of stomach cancer
- Surgery that involves the surgical removal of the tumors, partial removal of the stomach affected by cancer or a complete removal of the entire stomach.
- Chemotherapy that involves the intravenous use of special drugs that are designed to kill cancer causing cells
- Radiation therapy which employs intense and precision rays of radiation to destroy the cancer cells
Stomach cancer survival rate
The statistical analysis of survival rate for stomach cancer usually refers to the five year survival rate, which indicates the rate of survival for stomach cancer patients for a period of at least five years after initial diagnosis of the condition. One may also note that there are many patients who survive for more than five years.
The relative five year survival rate for stomach cancer patients refers to a comparison of the patients who have lived for five years after stomach cancer diagnosis to the general population ( of the same age, etc.) that has not been affected by the condition.
It is important to note that the survival rate for stomach cancer is just a statistic and cannot be generalized for all patients. Each case of stomach cancer is unique and the survival rate depends on a number of factors such as the type of stomach cancer, the response of the patient to the treatment, etc.
In the US, the five year survival rate for stomach cancer patients is an abysmal 28 percent, due to the fact that it is normally diagnosed in the advanced stages. Also, cancer of the lower stomach has a higher chance of survival as compared to cancer of the upper stomach
Provided below is the five year survival rate as per the different stages of stomach cancer for the time period between 1991 to 2000 and those which were treated via surgery. Treatment that does not involve surgery has a lower survival rate.
